Page 36: Application Notes
4. Application Notes In practice, users can use the two I-7540D-WF or a set of I-7540D-WF with the computer (with supporting for wireless network) connection structure in the application. It can complete the purpose of transferring CAN data to wireless network by this way. I-7540D-WF wireless connection can replace the cable, for some hard wiring or the CAN data transmission distance requirements, that is a very good option. -
Page 37: Hardware Installation
Step 1: Checking the I-7540D-WF firmware operation mode In the operation mode, the user can complete the wireless CAN data transmission via the I-7540D-WF. It needs to set the DIP switch to the Normal position (operating mode) as Figure 2-14; as resetting the power, I-7540D-WF will be in the operation mode. -
